You will be able to: Say which OSHA rule book covers a shop and which covers a jobsite, who OSHA covers in Texas, what the employer must do about PPE and what you do, and define competent person, qualified person, point of operation, energy isolating device and the noise terms.

Two rule books

This module cites Part 1910, Occupational Safety and Health Standards, for the shop.

It cites Part 1926, Safety and Health Regulations for Construction, for a jobsite and a roof.

OSHA wrote in 2001 that the activity, not the trade of the worker, determines which requirements apply.

OSHA defines roofing work to include related insulation, sheet metal and vapor barrier work.

Which OSHA rule book appliesFour panels. Shop work: 29 CFR Part 1910, with PPE, machine guarding, noise and lockout rules. Jobsite and roof work: 29 CFR Part 1926, with PPE, falls, ladders and noise rules. Texas is under federal OSHA, which covers most private-sector workers. The activity, not the trade, decides which rules apply.

Four panels. Shop work falls under 29 CFR Part 1910, with PPE, machine guarding, noise and lockout/tagout rules. Jobsite and roof work fall under Part 1926, with PPE, falls, ladders and noise rules. Texas is under federal OSHA, which covers most private-sector workers. The activity, not the trade, decides which rules apply, shown by the same red metal in a shop and on a roof. A band says there is no final federal heat rule and a heat emphasis program has been in effect since April 10, 2026.

Rule sections as cited in this module. The activity decides which applies (OSHA letter, 2001); the heat statement is as of 6 November 2026.

Glossary

Personal protective equipment (PPE)
Under 29 CFR 1910.132(a), equipment for the eyes, face, head and extremities, protective clothing, respiratory devices, and protective shields and barriers, provided, used and maintained in a sanitary and reliable condition wherever hazards make it necessary.
Competent person
Under 29 CFR 1926.32(f), a person who can identify existing and predictable hazards in the surroundings or working conditions and who has authorization to take prompt corrective measures to eliminate them.
Qualified person
Under 29 CFR 1926.32(m), a person with a recognized degree, certificate or professional standing, or extensive knowledge, training and experience, who has shown the ability to solve problems relating to the subject matter, the work or the project.
Point of operation
Under 29 CFR 1910.212(a)(3)(i), the area on a machine where work is actually performed upon the material being processed. Guarding must keep any part of the operator's body out of the danger zone during the operating cycle.
Energy isolating device
Under 29 CFR 1910.147(b), a mechanical device that physically prevents the transmission or release of energy. Push buttons, selector switches and other control circuit type devices are not energy isolating devices.
Action level (noise)
In a shop, 29 CFR 1910.95(c)(1) starts a hearing conservation program at an 8-hour time-weighted average sound level of 85 decibels, which the rule calls the action level.
State Plan
A state-run occupational safety and health program approved by OSHA. OSHA lists Texas as not an OSHA-approved State Plan, so federal OSHA covers most private-sector workers there.
